摘要： A collimator (100) for collimating radiation includes collimator material (150) and at least one collimator hole (110) defined by the surrounding collimator material (150). The collimator hole (110) defines an aperture (112) and a bottom surface (132) through which radiation can leave the collimator (100). The volume of the collimator hole between the aperture (112) and the entrance opening and/or exit opening is shaped such that there is at least one cross-section of the hole between the aperture (112) and the entrance opening and/or exit opening, the cross-section being taken parallel with the aperture, such that the shape of the cross-section of the hole cannot be obtained through an affine transform of the shape of the aperture.

摘要： A method for correcting a relaxation map of an object scanned with a magnetic resonance imaging modality the object having a plurality of structure and/or tissue types. The method includes deriving a first relaxation map of a scanned object from at least two three-dimensional scans of the object acquired using a sequence of ultrashort echo time pulses adapted for distinguishing between the various types of a plurality of structure and/or tissue types of the object. Information is obtained on the type of structure and/or tissue type present in voxels in the first relaxation map and binarizing the obtained information. A corrected relaxation map is generated by combining the binarized information with the first relaxation map.

摘要： A collimating system (100) for collimating radiation received under different angles for performing tomography is described. The collimating system (100) comprises a static collimator (110) comprising a plurality of collimating apertures (112), shutters (120) for separately and temporarily shutting at least two of said collimating apertures (112), wherein the shutters (120) having a shutting element (122) for blocking said at least two collimating apertures (112), and at least one collimating element (140) distinct from the shutting element (122) for collimating radiation passing through non-shut collimating apertures (112) in a direction so as to control overlap between radiation stemming from different non-shut collimating apertures (112). The invention also relates to an imaging system comprising such a collimating system, a method for collimating and a corresponding controller and software related products.
